Human Reliability and Process Safety Metrics: Considerations from an Abnormal Situation Management Perspective

The ASM Consortium conducted a series of studies investigating the role of operations practice failures in major process safety incidents.  The results of the studies improved our understanding of human reliability factors contributing to major process safety incidents.  The paper discusses the implications of these operations practice failure modes for process safety metrics. The paper includes recommendations on how process safety metrics could be enhanced to measure the effectiveness of operations practices and their potential impact on process safety performance.
